Filed: 1936-10-15
Abstract: 471,398. Valve circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 15, 1936, No. 28036. Convention date, Oct. 18, 1935. Drawings to Specification. [Classes 39 (i) and 40 (v)] A resistance is connected regeneratively in series with the cathode of an ultra-highfrequency tuned amplifier in order to neutralize variation of selectivity, due to the electron transit time, when the gain is varied by adjusting the grid bias. The amplifier in the absence of such correction behaves as if the cathode and control grid were connected by a resistance whose value varies with the gain, so that when the gain is varied by varying the grid bias, the damping and consequently the selectivity are varied correspondingly. According to the invention a resistance connected in series with the cathode is so dimensioned as to neutralize this effect. The added resistance is a function of the internal capacity between grid and cathode and of the transit time of the electrodes it may also take account of the capacity between the cathode and heater. The resistance in question may be incorporated in the valve.

Abstract: 1471226 Paper; modifying cellulosic fibres FELDMUHLE ANLAGEN-UND PRODUKTIONS GmbH 25 June 1974 [25 June 1973] 28195/74 Headings D2B and D2W [Also in Division C3] A process for the preparation of an aqueous dispersion of modified cellulose fibres comprises (a) treating cellulose fibres in aqueous dispersion with a cross-linking agent capable, on the application of heat, of cross-linking cellulose fibres, (b) heating the dispersion to effect at least partial cross-linking of the cellulose fibres, and (c) treating the dispersion of at least partially cross linked cellulose fibres with a polymer containing hydroxyl and/or amino groups, other than cellulose itself, or aldehyde condensates or other high M.W. substances capable of acting as crosslinking agents for cellulose. Paper may be made from the aqueous dispersion of modified cellulose fibres by conventional methods, the paper being characterized by its relatively high stiffness and bulk. The cross-linking agent may be formaldehyde, acetaldehyde, glyoxal, hexamethylene tetramine, or a melamine-formaldehyde or urea-formaldehyde precondensate e.g. dimethylol-urea, or a substance containing an epoxy group. In addition to the cross-linking agent, cyanamide may be added. The cross-linking reaction may be accelerated by the addition of an appropriate catalyst, and the reaction may be carried out by heating under pressure. The polymer containing hydroxyl and/or amino groups may be polyvinyl alcohol, a modified starch ether, or gelatine. When the polymer used is non-proteinaceous, a protein compound e.g. casein or soya bean protein may also be added. In the case where a melamine-formaldehyde precondensate is used as a cross-linking agent, the modified cellulosic fibres may be engine sized without rosin size e.g. ketene dimers. The paper made from the modified cellulosic fibres may be loaded with fillers.

As shown a gear connection 13 from the drum 1 rotates a cam 12 in accordance with the amount of cable paid out from the drum 1 so that the position of a cam follower 11 is varied to control the setting of a pressure reducing valve RV1 which can provide a range of pressure from a minimum high pressure to a maximum high pressure, constituting means for adjusting the high braking effort, being set for maximum high pressure with the maximum amount of cable paid out (i.e. when the load is approaching the bottom).  A second pressure reducing valve RV2 set to give a predetermined low pressure, e.g. about 10% of the supply pressure, is arranged in parallel with the valve RV1, both being connected to a changeover valve 18 controlled by a cable movement detector 16 coupled to the gear connection 13. The output from the valve 18 passes through a short delay orifice T1 in turn connected to two branch lines, each going to brake operating cylinder 4 via control valve 8, one by way of a valve 19 and the other by way of a long delay restricting orifice T2. The valve 19 is controlled by a cam 15 coupled to the gear connection 13 by a drive 13A and contoured so that follower 14 occupies one of two extreme positions, one being when the cable is nearly all paid out or nearly all wound in, the other (as shown) when the cable is between these extreme positions. A table (not shown) gives the braking effort, the braking pressure and the rate of application for the various conditions of the cable movement and positions of the load.
